Method and apparatus for correcting meter data for enhancement of electricity data management of photovoltaic module

A method of correcting meter reading data, the method comprising:

• reading energy usage of a consumer by a meter and transmitting meter data on the energy usage to an automatic meter reading (AMR) server;
• monitoring, by a meter data management system, an error in the transmitted meter data and a non-reading interval;
• re-requesting collection of an error in meter data and a non-reading interval to the AMR server;
• and
• correcting the error in the meter data and the non-reading interval using an estimated approximate value based on a history of previous meter data accumulated in a database of the AMR server when an error and a non-reading interval are found even after meter data is collected on the re-requesting,
• wherein the correcting of the error in the meter data and the non-reading interval corrects the error in the meter data and the non-reading interval using the error in the meter data and meter data at a start time and an end time of the non-reading interval and enhances the error in the meter data and the non-reading interval using a correction result after verifying that the correction result is included in a valid range of a history of previous meter data, and
• wherein the method defines linear functions touching a meter data pattern at points of ‘the start time of the error or the non-reading interval −a 1 unit time’ and ‘the end time of the error or the non-reading interval +a 1 unit time and acquires an intersecting point of the two linear functions.
